Abstract

The Raman spectra of polycrystalline Cr3O8 and Cr2O5 powders were measured. The powders were prepared by thermal decomposition of CrO3 under flowing oxygen. Their composition was verified with x-ray diffraction. Raman spectra were excited with both 514.5 nm and 647.1 nm radiation. The spectral intensities were corrected for wavelength-dependent instrumental response. Tentative peak descriptions were made by comparison of the Cr3O8 and Cr2O5 spectra with reported spectra of crystalline chromium oxides.
